Overview
The AD5754BREZ is a quad, 16-bit serial input voltage output digital-to-analog converter (DAC) from Analog Devices. It operates from single supplies of +4.5 V to +16.5 V or dual supplies of ±4.5 V to ±16.5 V. The device features software-programmable output ranges including +5 V, +10 V, +10.8 V, ±5 V, ±10 V, and ±10.8 V. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±16 LSB, a differential nonlinearity (DNL) error of ±1 LSB, and a typical settling time of 10 µs. It utilizes an iCMOS process technology and includes integrated reference buffers and proprietary power-up/power-down control circuitry.
Feature Summary
- Quad 16-bit resolution with guaranteed monotonicity
- Software-selectable unipolar/bipolar output ranges (+5 V to ±10.8 V)
- Integrated output amplifiers and reference buffers
- Simultaneous updating via LDAC pin for all four channels
Applications
- Industrial automation systems
- Closed-loop servo control applications
- Process control instrumentation
- Automotive test and measurement equipment
- Programmable logic controllers (PLCs)
Procurement Notes
Verify the specific suffix 'BREZ' against the manufacturer's ordering guide to confirm the B version accuracy grade and tube packaging format. Ensure that the external reference voltage source matches the specified REFIN range of 2 V to 3 V for optimal performance. Confirm that the system power supply rails fall within the absolute maximum ratings of AVDD/AVSS ±17 V and DVCC +7 V to prevent device damage.
Selection Notes
Select the AD5754BREZ when 16-bit resolution and simultaneous multi-channel updates are required. The B version offers tighter Total Unadjusted Error (TUE) specifications of ±0.1% FSR compared to the A version. Ensure the application supports the 24-lead TSSOP package dimensions and provides adequate thermal dissipation through the exposed paddle. Verify compatibility with the DSP/microcontroller-compatible serial interface operating up to 30 MHz.
Part Context
The AD5754 is part of the AD5724/AD5734/AD5754 family of complete quad DACs. While the AD5724 offers 12-bit resolution and the AD5734 provides 14-bit resolution, the AD5754 delivers 16-bit precision. All members share identical pinouts, serial interface protocols, and power supply requirements, allowing for design flexibility across different accuracy tiers within industrial and automotive applications.
Replacement Considerations
The AD5754AREZ serves as a direct functional replacement with identical pinout and specifications, differing only in the accuracy grade (A version vs. B version). Other family members like the AD5734BREZ offer lower resolution but maintain compatibility. No cross-family replacements are confirmed without verifying register-level and electrical parameter alignment.
